Description

Technical Field

[0001] The utility model belongs to the technical field of a neutralization tower, and more specifically, particularly relates to a neutralization tower used for producing a sodium nitrate solution. Background Art

[0002] Neutralization tower is a kind of equipment used to produce sodium nitrate solution. Its main function is to mix the conversion liquid and alkali solution evenly and fully to react them so as to continuously produce qualified sodium nitrate solution.

[0003] Based on the above, the inventors have found the following problems: when the current neutralization tower is in use, the nitric oxide gas produced by the reaction of the conversion liquid and the alkali solution will react with the alkali solution to generate sodium nitrite, thereby affecting the product quality. At the same time, the liquid film formed by the reaction of the conversion liquid and the alkali solution will hinder the reaction rate, increase the reaction time, and reduce the mixing efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a neutralization tower for producing sodium nitrate solution is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a neutralization tower for producing sodium nitrate solution, so as to solve the problems that the gas generated by the existing neutralization tower during the reaction may affect the product quality and the mixing efficiency is low.

[0006] The purpose and effect of the neutralization tower for producing sodium nitrate solution in the utility model are achieved by the following specific technical means:

[0007] A neutralization tower for producing sodium nitrate solution comprises a neutralization tower body, a vacuum mechanism and an aeration mechanism are installed on the surface of the neutralization tower body, a plurality of tower plates are installed inside the neutralization tower body, a baffle tube is installed on the surface of the tower plate, a partition plate is installed on the inner wall of the neutralization tower body, the partition plate is located above the tower plate, a feed pipe is installed on the surface of the neutralization tower, the feed pipe extends to the inside of the neutralization tower body, and a plurality of spray heads are installed on the surface of the feed pipe.

[0008] Furthermore, the baffles are distributed in a staggered manner.

[0009] Furthermore, the exhaust mechanism includes a vacuum pump, an air leakage pipe, an air collecting pipe, a main exhaust pipe, a first exhaust pipe and a second exhaust pipe. The vacuum pump is installed on one side of the neutralization tower body. The air leakage pipe is installed on the surface of the tower plate. The air collecting pipe is installed on the surface of the top tower plate. The main exhaust pipe is installed on the surface of the vacuum pump. The first exhaust pipe and the second exhaust pipe are installed on the surface of the main exhaust pipe. The first exhaust pipe is connected to the air collecting pipe, and the second exhaust pipe is connected to the top of the neutralization tower body.

[0010] Furthermore, the aeration mechanism includes an aeration fan, a first air pipe, a second air pipe, an aeration pipe and an aeration hole. The aeration fan is installed on one side of the neutralization tower body. The first air pipe is installed on the surface of the aeration fan. A plurality of second air pipes are installed on the surface of the first air pipe. The second air pipe extends into the neutralization tower body. An aeration pipe is installed on the surface of the second air pipe. A plurality of aeration holes are opened on the surface of the aeration pipe.

[0011] Furthermore, the height of the baffle tube is lower than the height of the leakage tube.

[0012] Furthermore, a discharge port is installed on the surface of the neutralization tower body.

[0013] Furthermore, the surface of the neutralization tower body is coated with an anti-rust coating.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model cooperates with a vacuum pump, an air leakage pipe, an air collecting pipe, a main air extraction pipe, a first air extraction pipe and a second air extraction pipe in use. When the spray head sprays, the vacuum pump is started. When the vacuum pump is started, the first air extraction pipe extracts waste gases such as nitric oxide generated during spraying out of the neutralization tower body. When the mixed liquid is mixed on the tower plate, the waste gases such as nitric oxide generated will drift upward from the air leakage pipe, and then the waste gases will be extracted out of the neutralization tower body through the second air extraction pipe. Through the above design, the waste gases such as nitric oxide generated by the mixing can be quickly discharged from the neutralization tower body, thereby avoiding the reaction of nitric oxide and alkali solution to generate sodium nitrite, thereby affecting the quality of the product.

[0016] Through the coordinated use of the aeration fan, the first air pipe, the second air pipe, the aeration pipe and the aeration holes, when the mixed liquid flows into the tower plate, the aeration fan is turned on. When the aeration fan is started, the generated gas will pass through the first air pipe, the second air pipe and the aeration pipe, and then be ejected from the aeration holes, thereby breaking the liquid film generated during the reaction. Through the above design, the reaction between the conversion liquid and the alkali solution can be accelerated and the reaction time can be shortened. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Through the coordinated use of the tower plate 2, the deflection tube 3, the partition plate 4, the feed pipe 5 and the spray head 6, the deflection of the multi-layer tower plate 2 can make the reaction more complete. Through the use of the partition plate 4, the waste gas generated by the tower plate 2 can be blocked from reacting with the alkali solution to affect the quality of the finished product, and the spray head 6 can improve the mixing degree of the mixed liquid.

[0028] Wherein, the baffle tubes 3 are distributed in a staggered manner.

[0029] Among them, the exhaust mechanism includes a vacuum pump 7, an air leakage pipe 8, an air collecting pipe 9, a main exhaust pipe 10, a first exhaust pipe 11 and a second exhaust pipe 12. The vacuum pump 7 is installed on one side of the neutralization tower body 1. The air leakage pipe 8 is installed on the surface of the tower plate 2. The air collecting pipe 9 is installed on the surface of the top tower plate 2. The main exhaust pipe 10 is installed on the surface of the vacuum pump 7.

The first exhaust pipe 11 is connected to the air collecting pipe 9, and the second exhaust pipe 12 is connected to the top of the neutralization tower body 1.

[0030] Through the coordinated use of the vacuum pump 7, the air leakage pipe 8, the air collecting pipe 9, the main air extraction pipe 10, the first air extraction pipe 11 and the second air extraction pipe 12, when the spray head 6 is spraying, the vacuum pump 7 is started.

[0036] The specific usage and function of this embodiment are as follows:

The mixed liquid is sprayed through the spray head 6, and the mixed liquid falls into the tower plate 2. When the height of the mixed liquid is higher than the baffle tube 3, the mixed liquid will flow into the next tower plate 2.

When the mixed liquid is mixed on the tower plate 2, the waste gas generated will drift upward from the leakage pipe 8, and then the waste gas will be extracted out of the neutralization tower body 1 through the second exhaust pipe 12.
